Abstract

In order to reduce a power transmission antenna and power receiving antenna of a wireless power supply device for supplying power underwater to a size suitable for an underwater mobile body and sensor, this underwater wireless power supply devicewirelessly transmits energy by resonating at a frequency determined by the impedance of a power transmission antennathat transmits energy wirelessly in a good conductor medium, the impedance of a power receiving antennawhich receives energy transmitted from the power transmission antenna, and the impedance of the good conductor medium. The power transmission antennaand the power receiving antennahave the multiple antenna coils, and at least one dielectricarranged between the multiple antenna coils, and the multiple antenna coilseach has multiple laminated coils
